Seven sisters A, B, S, D, R, L and G are standing in a row facing north. L is standing to the immediate right of R who stands fourth to the right of G. Only S stands exactly between B and D. D stands at the middle position. Who stands at the rightmost position?
Answer & explanation
Correct answer: option 2
Only S stands exactly between B and D. D stands in the middle position.
CASE 1:
_ B S D _ _ _
CASE 2:
_ _ _ D S D _
L is standing to the immediate right of R who stands fourth to the right of G.
CASE 1:
G B S D R L _
CASE 2:
It is not possible because in this case, R will be at the extreme right end. So, L cannot stand at the immediate right of R.
So, the only position for A is at the extreme right end.
G B S D R L A
∴ A is at the rightmost position.
